To all whom it may concern:

Be it known that I, WILLIAM A. R B- BINS, a citizen of the United States, residing at Waterbury, county of New Haven, State 6 of Connecticut, have invented acertain new and useful Im rovement in atal-Guides for Rolling-Mil s, of which the following is a full, clear, and exact description.

My invention relates to a guide for rolling mills of the type known as peg guides and has for its object to provide a guide which can be more easily operated than peg guides now in use. It further has for ts object to provide a guide in the operation of which there is less danger to the operator.

The purpose of a peg guideis to provide a device which shall exert a drag upon a strip of metal passing between the rolls of a rolling mill so as to guide it and maintain a tension thereon.

In the peg guides as heretofore employed, the movable portion of the guide when used is entirely separable from the machine and is removed therefrom every time a strip ofmetal is inserted. It is wedge shaped and is thrust between the strip of metal and suitable abutments, being dragged against the metal so as to exert a wedging action 80 thereon. After the metal has passed, the peg member is loose and can he removed to 'be reinserted whenthe next strip of metal reaches the rollers. This removal and insertion of'the peg requires great skill and dexterity and introduces an'element of danger to the operator.

In my improved guide the peg member is always under mechanical control and can be moved away and toward the metal by a simple crank action and yet performs the necessary functions of the peg member.

The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in

which,

Figure 1 shows a rear elevation of a peg guide embodying my invention, with a strip of metal inserted therein;

Fig. 2 shows a side elevation of the same,

the rolls of the rolling mill being shown diagrammatically.

Referring more particularly to the drawings, 1 is the ordinary peg guide supporting bar. 2-2 are castings constituting side members having holes surrounding the supporting bar 1 and adjustably secured thereto by set-screws 3-3. These side members at their ends adjacent to the rolls support a bar 4. Upon the bars 1 and 4. rests a plate 5 provided with a suitable surfacing pad 6, such as leather, canvas or the like suitably secured thereto. The plate 5 has projections 7 formed on a bent portion thereof engaging the rear faces of the side members 2-2 so as to prevent the plate 5 moving forward with the metal 8 which contacts therewith. 9 is a movable peg member provided with a pad 10 similar to the pad 6. Upon the portion 9 are lugs 11 and 12, through which pass bars 13 and 14, which bars extend through slots 15 and 16 forming guideways. The upper portions of these slots are inclined at an acute angle to the surface of the pad 6, while the lower portions of said slots curve gently until their lower ends are substantially parallel with the surface of the pad 6. From this it will be seen that if the peg member 9 is moved .to the rear by any means, therods 13 and 14 will ride up into the upper portions of the slots 15 and 16 and lift thepeg member 9, and that if a strip of metal is inserted between the pads 6 and 10 and the peg member 9 is moved to the right (Fig. 2), the metal will be clamped between the pads 6 and 10.

In order to mechanically move the peg member 9 in a simple manner, I provide a shaft 17 journaled in the side members 2-2', upon which is an actuating handle 18. This shaft is provided with a lever arm 19 which is connected by means of links 20 to the bar 14 of the peg member. A rearward movement of the handle 18 when the parts are in the position shown in Fig. 2

her so as to open the guidefor the insertion of a strip of metal and a movement in the reverse direction will close the guide so as to grip the sheet of metal and exert a tension't ereon as it is'being drawn through the rolls of the mill.

From the foregoingit will be seen that the movable member of the peg guide is always under positive mechanical control and that it can be safely and easily actuated by a simple crank motion.

The members 2-2 being adjustable upon the bar 1, parts of the same mechanism can be used for strips of varying widths by the adjustment of those parts and the substitu- 110 ans fications without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. In a peg guide for metal rolling mills, the combination of side pieces and a lower guide member supported thereby, an upper movable member adapted to be moved toward and from said lower member, said upper member having lateral projections and said side members having inclined ways en: gaged by said lateral projections soas to move said upper member toward and from sald lower member as it is reciprocated in one direction or the other.

2. In a peg guide for metal rolling mills, the combination of side pieces and a lower guide member supported thereby, an upper movable member adapted to be moved to ward and from said lower member, said upper member having lateral projections and said side members having inclined ways engaged by said lateral projections so as to move said upper member toward and from said lower member as it is reciprocated in one direction or the other, and means for mechanically reciprocating said peg member. Y

3. In a peg guide for metal rolling mills, the combination of side pieces and a lower guide member supported thereby, an upper movable member adapted to be moved toward and from said lower member, said upper member having lateral projections and 4. In a peg guide for metal rolling mills,

the combination of side pieces and a lower guide member supported thereby, an upper movable member adapted to be moved toward and from said lower member, said upper member having lateral projections and said side members having inclined ways engaged by said lateral projections so as to move said upper member toward and from said lower memberas it is reciprocated in onedirection or the other, a crank shaft carried by said side members and provided with. a lever, and links connecting said lever to said upper peg guide member.

5. In 'a peg guide for metal rolling mills, the combination of side pieces and a lower guide member supported thereby, an upper movable member adapted to be moved toward and from said lower member, said upper member having lateral projections and said side members having inclined ways engaged by said lateral projections so as to.

move said upper member toward and from said lower member as it is reciprocated in one direction or the other, said ways consisting of slots extending through said side members and said projections extending through said slots.
